# ADR-008 Implementation Plan

**Related ADR:** [ADR-008-sf-tools-over-mcp-for-provider-parity.md](./ADR-008-sf-tools-over-mcp-for-provider-parity.md)
**Status:** Rejected — never implement
**Superseded by:** docs/adr/0000-purpose-to-software-compiler.md + docs/dev/ADR-020-internal-wire-architecture.md
**Date:** 2026-04-09

## Superseded Boundary

Never build or restore an SF MCP server package.

Current SF product boundary:

- SF uses MCP only as a **client** for external tool servers configured through `.mcp.json` or `.sf/mcp.json`.
- SF workflow execution runs through native SF tools, headless/RPC, and the daemon/RPC client path.
- SF never exposes its workflow as an MCP server for Claude Code, Cursor, or other external clients.

This document is kept only as a tombstone for the rejected implementation plan. Do not revive this direction.
